The engine cooling system is filled at the factory
with a pre-diluted mixture of 50% Genuine
NISSAN Long Life Antifreeze/Coolant (blue) and
50% water to provide year-round antifreeze and
coolant protection. The antifreeze solution con-
tains rust and corrosion inhibitors. Additional en-
gine cooling system additives are not necessary.
WARNING
●Never remove the radiator or coolant
reservoir cap when the engine is hot.
Wait until the engine and radiator cool
down. Serious burns could be caused
by high pressure fluid escaping from
the radiator. For additional information
on precautions, refer to “If your vehicle
overheats” found in the “In case of
emergency” section of this manual.
● The radiator is equipped with a pres-
sure type radiator cap. To prevent en-
gine damage, use only a Genuine
NISSAN radiator cap.
CAUTION
● Never use any cooling system additives
such as radiator sealer. Additives may
clog the cooling system and cause dam-
age to the engine, transmission and/or
cooling system.
● When adding or replacing coolant, be
sure to use only Genuine NISSAN Long
Life Antifreeze/Coolant (blue) or
equivalent. Genuine NISSAN Long Life
Antifreeze/Coolant (blue) is pre-diluted
to provide antifreeze protection to -34°
F (-37° C) . If additional freeze protection
is needed due to weather where you
operate your vehicle, add Genuine
NISSAN Long Life Antifreeze/Coolant
(blue) concentrate following the direc-
tions on the container. If an equivalent
coolant other than Genuine NISSAN
Long Life Antifreeze/Coolant (blue) is
used, follow the coolant manufacturer’s
instructions to maintain minimum anti-
freeze protection to -34° F (-37° C) . The
use of other types of coolant solutions
other than Genuine NISSAN Long Life
Antifreeze/Coolant (blue) or equivalent
may damage the engine cooling
system. ●
The life expectancy of the factory-fill
coolant is 105,000 miles (168,000 km) or
7 years. Mixing any other type of cool-
ant other than Genuine NISSAN Long
Life Antifreeze/Coolant (blue) , includ-
ing Genuine NISSAN Long Life
Antifreeze/Coolant (green) , or the use
of non-distilled water will reduce the
life expectancy of the factory-fill cool-
ant. For additional information, refer to
the NISSAN Service and Maintenance
Guide.
ENGINE COOLING SYSTEM
Do-it-yourself8-5

CHECKING ENGINE COOLANT
LEVEL
Check the coolant levelin the reservoir when
the engine is cold. If the coolant level is below
the MIN level
B, add coolant to the MAX level
A. If the reservoir is empty, check the coolant
level in the radiator when the engine is cold. If
there is insufficient coolant in the radiator, fill the
radiator with coolant up to the filler opening and
also add it to the reservoir up to the MAX level
A.
This vehicle contains Genuine NISSAN Long Life
Antifreeze/Coolant (blue) . The life expectancy of
the factory-fill coolant is 105,000 miles (168,000 km) or 7 years. Mixing any other type of
coolant or the use of non-distilled water will re-
duce the life expectancy of the factory-fill coolant.
For additional information, refer to the NISSAN
Service and Maintenance Guide.
If the cooling system frequently requires
coolant, have it checked. It is recom-
mended that you visit a NISSAN dealer for
this service.
For additional information on the location of the
engine coolant reservoir, refer to “Engine com-
partment check locations” in this section.
CHANGING ENGINE COOLANT
A NISSAN dealer can change the engine coolant.
The service procedure can be found in the
NISSAN Service Manual.
Improper servicing can result in reduced
heater performance and engine overheat-
ing.
WARNING
●
To avoid the danger of being scalded,
never change the coolant when the en-
gine is hot.
● Never remove the radiator or engine
coolant reservoir cap when the engine
is hot. Serious burns could be caused by
high pressure fluid escaping from the
radiator.
● Avoid direct skin contact with used
coolant. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep coolant out of the reach of chil-
dren and pets.
Engine coolant must be disposed of properly.
Check your local regulations.

CHECKING ENGINE OIL LEVEL
1. Park the vehicle on a level surface and applythe parking brake.
2. Start the engine and let it idle until it reaches operating temperature.
3. Turn off the engine. Wait more than
10 minutes for the oil to drain back into
the oil pan.
4. Remove the dipstick and wipe it clean. Re- insert it all the way. 5. Remove the dipstick again and check the oil
level. It should be between the H (High) and
L (Low) marksB. This is the normal oper-
ating oil level range. If the oil level is below
the L (Low) mark
A, remove the oil filler cap
and pour recommended oil through the
opening. Do not overfill
C.
6. Recheck oil level with the dipstick.
It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the severity
of operating conditions.

CAUTION
●Oil level should be checked regularly.
Operating the engine with an insuffi-
cient amount of oil can damage the
engine, and such damage is not covered
by warranty.
● It is normal to add some oil between oil
maintenance intervals or during the
break-in period, depending on the se-
verity of operating conditions.
Make sure to follow the engine oil changing inter-
vals in the maintenance booklet. Operating under
the following conditions may require more fre-
quent oil change: ● repeated short distance driving
● driving in dusty conditions
● stop and go commuting.
CHANGING ENGINE OIL
1. Park the vehicle on a level surface and apply
the parking brake. 2. Start the engine and let it idle until it reaches
operating temperature, then turn it off.
3. Remove the oil filler capAby turning it
counterclockwise.

4. Place a large drain pan under the drain plug
B.
5. Remove the drain plug
Bwith a wrench by
turning it counterclockwise and completely
drain the oil.
If the oil filter is to be changed, remove and
replace it at this time. For additional informa-
tion, refer to “Changing engine oil filter” in
this section.
WARNING
● Prolonged and repeated contact with
used engine oil may cause skin cancer.
● Try to avoid direct skin contact with
used oil. If skin contact is made, wash
thoroughly with soap or hand cleaner as
soon as possible.
● Keep used engine oil out of reach of
children.
CAUTION
● Be careful not to burn yourself. The en-
gine oil may be hot.
● Waste oil must be disposed of properly.
● Check your local regulations. 6. Clean and reinstall the drain plug and a new
washer. Securely tighten the drain plug with
a wrench. Do not use excessive force.
Drain plug tightening torque: 34 N·m (25 ft-lb)
7. Refill engine with recommended oil through the oil filler opening, then install the oil filler
cap securely.
For additional information on the drain and
refill capacity, refer to “Recommended
fluids/lubricants and capacities” in the
“Technical and consumer information” sec-
tion of this manual.
The drain and refill capacity depends on the
oil temperature and drain time. Use these
specifications for reference only. Always use
the dipstick to determine when the proper
amount of oil is in the engine.
8. Start the engine. Check for leakage around the drain plug and oil filter. Correct as re-
quired.
9. Turn the engine off and wait more than 10 minutes. Check the oil level with the
dipstick. Add engine oil if necessary.
For additional information on the location of the
engine oil filler cap, refer to “Engine compartment
check locations” in this section.CHANGING ENGINE OIL FILTER
